Background/Purpose
This study aimed to evaluate how a two-week program using the in-phase mode of a balance adjustment system (the BASYS) affected postural control in participants with chronic ankle instability (CAI). It was hypothesized that the in-phase mode on the BASYS would lead to improved postural control compared with training on a balance...

Context 1
... assess static postural control, all participants stood on an instrumented BASYS (MPF-5050B; Tec Gihan Co., Ltd., Kyoto, Japan) in a single-limb stance (CAI limb only) with their hands crossed in front of their chest and their eyes closed ( Figure 3). They were given the following instructions: "Remain as motionless as possible for 30 sec, and if you move out of position, please return to the original position as soon as possible and continue the trial." ...
Context 2
... exercises were carried out only on the unstable ankle and were performed barefoot. Participants in the BASYS group trained using the in-phase mode on the BASYS (Figure 3), whereas participants in the BD group trained with the DynaDisc on the floor. The BASYS used the anterior-posterior position of the COP in the standing position as a feedback signal to immediately move the floor surface in the front-back direction. ...

... Dynamic and unstable balance training have been reported to be an effective modality for improve the symptoms of ankle instability and promote proprioceptive recovery in clinical practice (Yoshida, Kuramochi et al. 2023). A review concluded that balance training effectively reduces the risk of ankle sprain in sports participants (Schiftan, Ross et al. 2015). ...
Conclusion: Balance training benefits ankle function with CAI patients and improve the dynamic balance ability. It is recommended to obtain the best rehabilitation effect by intervening 3 times a week, each intervention time of 20min to 30min, and consecutively intervening for 4 weeks or 6 weeks.
Objective: To investigate and contrast the effects of balance training on ankle function and dynamic balance ability in patients with chronic ankle instability (CAI).
Methods: The PubMed, Embase, Web of Science, Medline, Cochrane were searched up to December 2023. Quality assessment was performed using the Cochrane Collaboration’s risk-of-bias guidelines, and the standardized mean differences (SMD) or mean differences (MD) for each outcome were calculated.
Results: Among 20 eligible studies, including 682 participants were analyzed in this meta-analysis. The results of the meta-analysis showed that balance training was effective in improving ankle function with self-functional scores (SMD =1.02 ; 95% CI,0.61 to 1.43;P < 0.00001; I² = 72%) and variables associated with the ability of dynamic balance such as SEBT-A (MD=5.88; 95% CI, 3.37 to 8.40; P<0.00001; I2 = 84%), SEBT-PM (MD=5.47; 95% CI, 3.40 to 7.54; P<0.00001; I² = 61%), and SEBT-PL (MD=6.04; 95% CI, 3.30 to 8.79; P<0.0001; I² = 79%) of CAI patients. Meta-regression showed that the intervention time may be the main reason for heterogeneity (P=0.046) in self-functional scores. In subgroup analyses of self-functional score across intervention types, among the intervention time, more than 20 minutes and less than 30 minutes had the best effect(MD=1.21, 95% CI: 0.96 to 1.46, P<0.00001，I²=55%);among the intervention period, 4 weeks (MD=0.84, 95% CI:0.50 to 1.19, P<0.00001，I²=78%)and 6 weeks (MD=1.21, 95% CI: 0.91 to1.51, P<0.00001，I²=71%) had significant effects; among the intervention frequency, 3 times (MD=1.14, 95% CI:0.89 to 1.38), P<0.00001，I²=57%)had significant effects. Secondly, in subgroup analyses of SEBT across intervention types, a 4-week and 6-week intervention with balance training 3 times a week for 20-30 min is the best combination of interventions to improve SEBT (dynamic balance) in patients with chronic ankle instability.
Conclusion: Balance training benefits ankle function with CAI patients and improve the dynamic balance ability. It is recommended to obtain the best rehabilitation effect by intervening 3 times a week, each intervention time of 20min to 30min, and consecutively intervening for 4 weeks or 6 weeks.

... The potential benefits are manifold -enhanced athletic performance, reduced risk of recurrent ankle injuries, and improved overall quality of life for the athletes. Such insights are invaluable not only for the athletes themselves but also for sports medicine professionals, physiotherapists, and basketball coaches who are instrumental in the rehabilitation and training processes (23,24). Ultimately, this research could lead to more targeted, effective treatment and training strategies, catering specifically to the needs of basketball players with chronic ankle instability, thereby ensuring their continued engagement in the sport and enhancing their overall well-being. ...
Background: Ankle sprains, which often lead to chronic ankle instability (CAI), are common within the young, athletic population, particularly among basketball players. Rehabilitation programs frequently employ hop stabilization and balance training to mitigate the complications associated with CAI. This research was undertaken to compare the effectiveness of these two training approaches in improving disability and balance in affected individuals.
Objective: The study aimed to evaluate and contrast the impact of hop stabilization versus balance training on disability and balance in basketball players with CAI.
Methods: The randomized clinical trial was conducted at Ranger’s Teaching Hospital in Lahore, targeting young basketball players aged between 25 to 35 years with a history of recurrent ankle sprains and at least 8 months of playing experience. Through a non-probability convenient sampling technique, the participants were randomized into two groups: Group A underwent 6 weeks of hop stabilization training in addition to general training, while Group B participated in 6 weeks of balance training coupled with their general training regimen. The efficacy of these interventions was quantified using the Star Excursion Balance Test, Functional Ankle Disability Index, Functional Ankle Ability Measure questionnaire, and Multiple Single Leg Hop Stabilization Test (MSLHST).
Results: Post-training assessments within groups indicated significant enhancements in disability and balance scores, with p-values below 0.05, suggesting notable improvements. However, when comparing the two groups, the Functional Ankle Ability Measure, Ankle Disability Index, and Star Excursion Balance Test showed no significant differences, with p-values exceeding 0.05. Notably, the MSLHST exhibited a significant contrast, with Group B showing a mean score decrease from 10.7857 to 5.7857, reflecting a 46% improvement, whereas Group A displayed a reduction in mean score from 13.625 to 11.7, a 14% enhancement, resulting in a significant p-value of 0.0289.
Conclusion: The study concluded that balance training surpasses hop stabilization training in terms of efficacy, significantly improving balance and reducing disability in basketball players with chronic ankle instability.
